“…A slight shift is noticed between 2918 cm À1 and 2919 cm À1 , and between 2849 cm À1 and 2850 cm À1 , as function of the immersion time for n a (-CH 2 ) and n s (-CH 2 ) respectively which is not significant regarding the spectral resolution of the spectrometer. By comparison with n-dodecanethiol and n-dodecanselenol SAMs on electroreduced copper previously reported [29], PM-IRRAS spectra of (S-Se) and (Se-S) monolayers are not different and indicate well-organised molecular films. At this level of characterization we can advance two hypotheses.…”

“…Similar experiments on copper-supported monolayers of thiolates and selenolates did not show strong preferences for either chalcogen. 74,75 Substrates can also be engineered to promote exchange. 76,77 Place exchange between adsorbed thiolates is generally slow in full-coverage monolayers.…”

Exchange Reactions between Alkanethiolates and Alkaneselenols on Au{111}

When alkanethiolate self-assembled monolayers on Au{111} are exchanged with alkaneselenols from solution, replacement of thiolates by selenols is rapid and complete, and is well described by perimeter-dependent island growth kinetics. The monolayer structures change as selenolate coverage increases, from being epitaxial and consistent with the initial thiolate structure to being characteristic of selenolate monolayer structures. At room temperature and at positive sample bias in scanning tunneling microscopy, the selenolate–gold attachment is labile, and molecules exchange positions with neighboring thiolates. The scanning tunneling microscope probe can be used to induce these place-exchange reactions.
